anion gap The Anion Gap is an approximate measurement of ions, that is molecules with a charge, either negative or positive. Sodium and potassium are positively charged and therefore called cations; this is why they are often represented as Na + and K + respectively.
A normal anion gap (6-12 mEq/L) may indicate the following: 1  Loss of bicarbonate (ie, diarrhea) 2  Recovery from diabetic ketoacidosis. 3  Ileostomy fluid loss. 4  Carbonic anhydrase inhibitors (acetazolamide, dorzolamide, topiramate) 5  Renal tubular acidosis. 6  Arginine and lysine in parenteral nutrition. 7  Normal variant.
